Lethal in combination with Df(3R)fru4-40.
Viable in combination with Df(3R)P14. Df(3R)fruw24/Df(3R)ChaM5 animals die as embryos.
Df(3R)ChaM5/In(3R)fru heterozygotes exhibit a muscle of Lawrence defect. In Df(3R)ChaM5/Df(3R)P14 heterozygotes muscle of Lawrence-position fibres have fewer nuclei than medial fibres.
When heterozygous with In(3R)fru males are behaviourally sterile, form courtship chains and have an intermediate "muscle of Lawrence" (MOL) phenotype: slight thickening or slightly altered insertion sites of the longitudinal muscles.
Homozygous lethal.
When heterozygous with fru, males are sterile and exhibit chain behaviour.
